Former President Joe Biden has been diagnosed with an aggressive form of prostate cancer that has spread to his bones, his office confirmed in a statement released Sunday afternoon.

The news follows weeks of growing concern and speculation about his health and marks a significant moment in the current political landscape.

Doctors made the diagnosis on Friday after detecting a small nodule on Biden’s prostate during an exam prompted by worsening urinary symptoms.

According to the statement, the cancer was classified with a Gleason score of 9 (Grade Group 5), indicating a high-grade, fast-growing tumor.

Despite the seriousness of the diagnosis, the cancer is said to be hormone-sensitive—a detail that could make it more responsive to certain treatment options.
